Caulking Services in Niagara Region

Most residential caulking jobs range from $150–$400 depending on the number of areas, the condition of existing caulk, and whether any mould or water damage needs to be addressed first. A single bathtub or shower surround is typically on the lower end, while whole-bathroom, kitchen, and exterior window caulking across multiple areas is priced by scope.

Look for visible cracks, gaps, peeling edges, or areas where the caulk has pulled away from the tile, tub or frame. In bathrooms and showers, black or dark spots indicate mould growth behind or within the caulk. If you notice water pooling where it shouldn't, feel drafts around windows, or see discolouration spreading along sealant lines, it's time for replacement. Catching it early prevents rot, mould and much more expensive repairs.

Yes — we completely remove old, failed, or mouldy caulk before applying new silicone. We carefully cut out the old material, clean and dry the surface thoroughly, treat any mould-affected areas, and then apply fresh, high-quality kitchen-and-bath or exterior-grade silicone that is properly tooled for a clean, professional, lasting seal.

We use premium silicone caulks designed specifically for wet and high-use environments. For bathtubs, showers and sinks, we apply 100% silicone because it stays flexible, resists mould growth, and handles the temperature swings and constant moisture of daily use without cracking or shrinking. For kitchens and other areas, we select the right product based on the substrate and exposure level, ensuring a durable, professional finish every time.

Absolutely. Proper caulking is one of the most cost-effective ways to prevent water intrusion and the damage it causes. Sealed bathtubs, showers, windows, door frames and exterior joints stop moisture from getting into walls, subfloors and framing where it can cause rot, mould and structural deterioration. For landlords and property managers in St. Catharines, Welland and Niagara Falls, maintaining caulk between tenants is an easy way to protect against expensive repairs later.
